I don't even know how to find this out... I set all of this up 5 years
ago, and don't use Erlang very much anymore, so I'm having to relearn
a lot of this. [blush]

You should be able to run

yaws --version

from your command line to obtain the version.

They all look fine to me.

Under your $HOME/.yaws directory do you have a file named CTL, and if so, is it 0-length? If so, try deleting that file and then restarting Yaws.

Also, I have another question: are you aware of anything that changed recently on your host to cause your installation to stop working?
